The new version is posted in English and Spanish on CMS’ Beneficiary Notices Initiative (BNI) webpage at https://www.cms.gov/medicare/forms-notices/beneficiary-notices-initiative and Health Plan’s website under Advantage D-SNP Forms at https://www.hpsj.com/forms-documents/.
- No changes were made to the MOON delivery or timeframe requirements.
- CMS made readability and design improvements for consistency with other Medicare notices.
- The updated MOON is effective now and expires February 28, 2029.

Providers are required to deliver a MOON to Medicare members (including Health Plan Medicare Advantage D-SNP members) informing them that they are outpatients receiving observation services and are not inpatients of a hospital or critical access hospital (CAH).
